- The second moon that Earth has captured in its orbit this month is an asteroid called 2024 PT5.
- Mini-moons like this could be ideal targets for asteroid mining to send humans deeper into space.
- Space mining could be huge, since some asteroids are worth more than our entire global economy.
The second moon that Earth now has for two months may seem like just a fun curiosity, but it's also a sneak peek at a future space industry that could change our global economy.
